Utilizing Exhaled Breath and Skin Microbiomes in Assessments of At‐Risk Killer Whales (Orcinus orca)

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT For at‐risk populations of killer whales (Orcinus orca), biological samples can offer information about individual animal status. We hypothesized that low‐yield samples could provide sufficient material for microbiome analysis. We collected and analyzed, with amplicon metabarcoding, breath samples from managed care and free‐ranging killer ...

Adhesive threads of extraintestinal pathogenic Escherichia coli

Gut Pathogens, 2009
The ability to adhere to host surfaces is by far the most vital step in the successful colonization by microbial pathogens. Colonization begins with the attachment of the bacterium to receptors expressed by cells forming the lining of the mucosa.

In vitro effect of subinhibitory concentrations of ceftazidime and meropenem on the serum sensitivity of Pseudomonas aeruginosa strains [PDF]

, 2007
The aim of this study was to determine the effect of subminimal inhibitory concentrations (subMICs) of ceftazidime, meropenem and gentamicin on the in vitro serum sensitivity of Pseudomonas aeruginosa strains isolated from a variety of isolation sites at

The role of the motility of Methylobacterium in bacterial interactions in drinking water [PDF]

, 2018
Bacterial motility is one important factor that affects biofilm formation. In drinking water there are key bacteria in aggregation, whose biology acts to enhance the formation of biofilms. However, it is unclear whether the motility of these key bacteria

Taurocholic Acid Is Associated With Disturbed Functional Connectivity in the Hippocampus of Patients With Depression

Advanced Science, Volume 13, Issue 13, 3 March 2026.
This study identifies elevated taurocholic acid (TCA) in Major Depressive Disorder patients. Gut microbiome‐associated TCA impairs hippocampal neurogenesis, triggers microglia activation, and elicits depression‐like behavior in mice via the S1PR2. In patients, functional neuroimaging reveals that serum TCA levels correlate with altered functional ...

Engineered Probiotics: The Next‐Generation Therapeutics to Combat Antibiotic‐Resistant Bacterial Infections

Food Frontiers, Volume 7, Issue 2, March 2026.
Engineered probiotics secretes fusion proteins which potentially neutralized the toxins secreted by other microbial communities. ABSTRACT On a global scale, the escalating burden of infectious diseases, predominantly attributed to bacterial pathogens, especially drug‐resistant strains, has progressed into a critical concern for clinical management and ...

Type 1 fimbriae-mediated collective protection against type 6 secretion system attacks

mBio
Bacterial competition may rely on secretion systems such as the type 6 secretion system (T6SS), which punctures and releases toxic molecules into neighboring cells.

Phosphorylated OmpR Is Required for Type 3 Fimbriae Expression in Klebsiella pneumoniae Under Hypertonic Conditions

Frontiers in Microbiology, 2018
OmpR/EnvZ is a two-component system that senses osmotic signals and controls downstream gene expression in many species of Enterobacteriaceae. However, the role of OmpR/EnvZ in Klebsiella pneumoniae remains unknown.

Characterization of two homologous disulfide bond systems involved in virulence factor biogenesis in uropathogenic Escherichia coli CFT073 [PDF]

, 2009
Disulfide bond (DSB) formation is catalyzed by disulfide bond proteins and is critical for the proper folding and functioning of secreted and membrane-associated bacterial proteins.

Interkingdom Interactions in the Gut: Ecological Mechanisms, Homeostasis, and Therapeutic Modulation

Gut Medicine, Volume 2, Issue 1, Page 23-39, March 2026.
ABSTRACT The gut microbiota constitutes a highly complex and dynamic ecosystem that profoundly influences host physiology, metabolism, and immunity. This review provides an integrative overview of the mechanisms through which gut microorganisms—particularly bacteria and fungi—interact with host cells and with each other to maintain intestinal ...
